Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern is repeated throughout the circumference of the tire tread, as shown schematically by solid lines, the opposite side being substantially the same as that illustrated; and,

FIG. 2 is a enlarged fragmentary view of the tread pattern of the tire tread of my design as shown in FIG. 1.

The broken line disclosure of a tire bead and sidewall is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
